I do not like this site because of the camera review something?Give only four stars , both real feelings .This camera should have a score of five stars.But read the review and analysis Web presentation was very good.Before I decide to buy Canon EOS 70D.

The good: The Canon EOS 70D's new sensor delivers excellent autofocus performance and the camera itself is quite fast. Its design is reasonably streamlined and the feature set appropriately tailored to the target market as well.
The bad: The image quality doesn't overly impress for this price class, and certain aspects of the design -- notably single card slot, hard-to-control multi controller and the Wi-Fi/movie mode conflict resolution -- are annoying.
The bottom line: An overall excellent camera, but one that fails to capture the best-in-class prize for image quality.
 
Editors' note: This is an updated version of my preproduction preview with ratings, final image samples, and performance numbers.
There's so much to like about the eagerly awaited replacement for the Canon EOS 60D, the 70D. It comes with a completely overhauled, Live View/video-optimized autofocus system that doesn't require special lenses; a more streamlined body design with an articulated touch screen; and Wi-Fi support. And with only a couple of exceptions, I like the 70D and enjoy shooting with it; it's fast and fluid. However, pixel peepers will likely be disappointed with the still photo quality, which really should be better for the money.
Image quality
The image quality didn't change noticeably between my preproduction tests and my final tests, but my opinion has. It's...fine. Not outstanding for the money, but not bad, either. However, it's simply not as good as the Nikon D7100. Yes, it's still an advance over the 60D, but not enormously -- I don't think you even gain a full stop of usability, and any advantages seem to stem from the slight increase in resolution. It's a bit better than the Rebel T5i across the entire sensitivity range, though you really have to scrutinize them. (The T5i looks better starting at ISO 1600, but that seems to be because the T5i meters a third of a stop brighter.)
I'm beginning to think Canon really pushes the contrast on its default Picture Style to increase perceived sharpness of the photos, because when you look at details closely they seem awfully soft. You lose a lot of shadow and highlight detail if you leave the Picture Style on Auto, though. The dynamic range doesn't seem especially wide, without a lot of recoverable highlight data in the raw files and shadows that are difficult to bring up without introducing noise. The new sensor does seem to have a finer noise pattern at higher ISO sensitivities than previous sensors, though.

Where to Buy

Thanks for the review Canon EOS 70D from cnet.com.
